Fertilizer distributor



Feb. 3, 1942. A. F. THORNTON FERTILIZER- DISTRIBUTOR Filed July 6, 1940INVENTOR. A. F. THORNTON Patented Feb. 3, 1942 UNITED STATES PATENTOFFICE 3 Claims.

This invention relates to improvements in fertilizer distributorattachments.

The general object of the invention is to provide a fertilizerdistributor attachment having a novel housing.

A more specific object of the invention is to provide a fertilizerdistributor attachment including a novel housing having a novel coremember frictionally engaged within the housing.

Another object of the invention is to provide a novel fertilizerdistributor attachment including a metal housing having a resilientmolded core member in which all of the necessary conduits are molded atthe time of manufacture.

Other objects and the advantages of my invention will be apparent fromthe following description taken in connection with the accompanyingdrawing, wherein:

Fig. 1 is a side elevational view of a water hydrant with the fertilizerdistributor attachment and associated parts arranged thereon;

Fig. 2 is a central sectional view of the fertilizer distributorattachment;

Fig. 3 is a bottom plan view of the fertilizer distributor attachment;

Fig. 4 is an elevational view of the fertilizer distributor attachmentlooking towards the right on Fig. 2;

Fig. 5 is an elevational View of the fertilizer distributor attachmentlooking towards the left on Fig. 2; and

Fig. 6 is a fragmentary side elevational view with parts broken awayshowing the core being inserted.

Referring to the drawing by reference characters I have indicated myimproved fertilizer distributor generally at Ill. As shown thefertilizer distributor attachment includes a housing II made of asuitable metal or the like and a resilient cylindrical inner core memberI2 which is preferably made of relatively hard rubber.

The fertilizer distributor attachment I is so constructed as to allowthe housing I I to be manufactured as a comparatively rough castingwhich only requires threading. The core member I2 which includes arather complex conduit arrangement is preferably made as a molded rubberproduct with the conduits molded in place as it may be made of resilientmaterial and machined.

The housing II includes a cylindrical portion I3 having an externallythreaded portion I4 at one end and an axially aligned enlarged headportion I at the other end thereof. The portions I3 and I5 includecentrally aligned bores I6 and H. The bore I! is provided with internalthreads I8 and is somewhat larger than the bore I6 thus providing ashoulder I9 therebetween. The housing II further includes a laterallyarranged cylindrical portion 20 located adjacent the'portions I3 and I5and which extends outwardly therefrom. The portion 20 is provided withan aperture 2I which communicates with the bore I6 through a reducedinlet aperture 22 in the housing.

The aperture 2| threadedly receives a connecting member 23 whichincludes a hollow stem portion 24 and an enlarged hexagonal headedportion 25.

The core member I2 includes a flared opening 28 at one end communicatingwith a centrally located aperture 29 which in turn communicates with oneend of an elongated flared portion 30 opening out the end remote fromthe flared portion 28. At the junction of the flared portion 30 and theaperture 29 the portion 30 is slightly larger than the aperture thusproviding a shoulder 32.

An aperture 33 in the core is aligned with, and communicating with, theflared portion 30 at the intersection of the portion 30 and the aperture29 through a reduced inlet aperture 34.

The core member I2 is forced into the bore I6 preferably after it isfinished (see Fig. 6) and is advanced until the core reaches theposition shown in Fig. 2 wherein the aperture 33 communicates with theaperture 22 and in turn with the hollow stem portion 24.

In use the fertilizer distributor I0 is secured to a water hydrant 35(see Fig. 1) by the threaded portion IS. The threaded portion I4 on thehousing I I in turn engages one end of a hose 36 provided with asuitable nozzle 31. A tube 38 has one end connected to the stem 24 andthe other end communicating with a receptacle 39 which contains suitableliquid fertilizer.

The water from the hydrant passing over the shoulder 32 in the coremember I2 produces a partial vacuum thus syphoning the fertilizer fromthe container 39 which in turn mixes with the waterand is sprayed wheredesired through the nozzle 31.

From the foregoing it will be apparent that I have invented a novelfertilizer distributor which can be economically made and which ishighly efiicient for its intended purpose.

Having thus described my invention, I claim:

1. In a fertilizer distributor attachment including a housing and a coremember, said housing including a cylindrical body portion having ahollow head portion thereon, threads in said hollow portion and on saidcylindrical portion, a laterally extending cylindrical portion on saidhousing and having an internally threaded aperture and a smalleraperture communicating with the interior of said body, a connectingmember threadedly secured in said threaded aperture, said core memberincluding a central aperture communicating with one end thereof andhaving a flared portion communicating with the central aperture andopening out of the other end of the core member, said core member havingan inlet aperture arranged at right angles to the axis of the coremember and having a reduced inlet aperture communicating with saidflared portion and said inlet aperture, said inlet apertures beingaligned with said laterally extending cylindrical portion.

2. In a fertilizer distributor attachment including a housing and a coremember, said housing including a cylindrical body portion having anenlarged head portion thereon, said cylindrical portion and saidenlarged head portion having aligned bores, the bore in said enlargedportion being larger than the bore in said cylindrical portion, internalthreads in said enlarged portion and external threads on saidcylindrical portion remote from said enlarged portion, a laterallyextending cylindrical portion on said housing adjacent said enlargedportion, said last mentioned cylindrical portion having an outeraperture and having a smaller aperture affording communication betweensaid outer aperture and the interior of said body portion, a connectingmember secured in said outer aperture, said connecting member having ahollow stem, said core member including a flared open inner end andhaving a central aperture communicating with the inner end of saidflared end, said core member including a second portion reversely flaredwith respect to the first mentioned flared portion and communicatingwith and axially aligned with said central aperture and opening out ofthe end remote from said first mentioned flared end, a shoulder formedbetween said last mentioned flared portion and said central aperture,said core having an outer inlet aperture and having a reduced innerinlet aperture communicating with said second mentioned flared portionand said outer inlet aperture, said inlet apertures being aligned withsaid threaded aperture in the laterally extending cylindrical portion.

3. In a fertilizer distributor attachment including a housing and a coremember, said housing including a cylindrical body portion having anenlarged head portion thereon, said cylindrical portion and saidenlarged head portion having aligned bores, the bore in said enlargedportion being larger than the bore in said cylindrical portion, internalthreads in said enlarged portion and external threads on saidcylindrical portion remote from said enlarged portion, a laterallyextending cylindrical portion on said housing adjacent said enlargedportion, said last mentioned cylindrical portion having an internallythreaded cylindrical aperture and having a smaller aperturecommunicating therewith, said body having a reduced aperture affordingcommunication between said smaller aperture and the interior of saidbody, a connecting member threadedly secured in said threaded aperture,said connecting member including a hollow stem member, said connectingmember and said stem including a bore therethrough, said core memberincluding a flared open inner end and having a central aperturecommunicating with the inner end'of said flared end, said core memberincluding a second portion reversely flared with respect to the firstflared portion and communicating with and axially aligned with saidcentral aperture and opening out of the end remote from said firstmentioned flared end, a shoulder formed between said last mentionedflared portion and said central aperture, said core having an inletaperture of less diameter than said reduced aperture and arranged atright angles to the axis of the core and having a reduced inlet aperturecommunicating adjacent said shoulder with said second mentioned flaredportion and said inlet aperture, said core member being frictionallysecured in said housing bore, said inlet apertures being incommunication with but out of alignment with said head member bore.
